HERMAN WHITNEY AND ELMER WHITNEY, OF NARKA, KANSAS.

ROAD-GRADING: MACHINE.

Specification of Letters Patent.

Patented May 26, 1914.

Application filed October 4, 1912. Serial No. 723,990.

To all whom it may concern i Be Vit known that we, HERMAN WHITNEY and ELMER WHITNEY, citizens of the United States, residin at Narka, in the county of Republic and tate of Kansas, have invented certain new and useful Improvements in Road-Grading Machines, of which the following is a specification.

The object of our invention is to provide a combined road grading, ditching, leveling and rolling machine in which4 the grading and ditching devices are exibly connected so as to grade a road at any desired angle; and with this and minor objects in view, our invention consists in the parts and combination of parts as will be hereinafter more fully set out. n

In the drawing-Figure 1 is a perspective view of a road grading machine embodying our invention; Fig. 2 is a similar view from the opposite side of the machine; Fig. 3 is a perspective view looking of the machine; Fig. 4 is a detail perspective view of parts of the machine; Fig. 5 is a detail perspective plan view. Fig. 6 is a diagrammatic view.

The reference numeral 1- designates a fiame of Suitable construction and preferably of triangular shape having suitable ears br hinge members 2 on one of its sides, to which the hinge members 3 are connected by means of a suitable bolt. The hinge 4. It will be seen-that the two rear members of the frames. 1 and 4 are set tangent to the line of draft of the machine. The frame 1 is adapted to be connected in any suitable manner to a traction engine whereby it may be moved along the road. I

5 is a wheel journaled upon a shaft 6 in the frame 1.

7 is a wheel journaled upon a shaft 8 in the frame 4, said wheels sustaining the weight of their respective frames.

-9 is a traction wheel journaled upon an axle 10, the other end of which is secured to the frame l.

1l is a cross beam extending across the frame 1, on which is mounted a bracket 12.

13 is a beam secured to the bracket 12 and extending rearwardly and suitably supported by braces on top of the frame 1, the rear end thereof being deflected inwardly at an angle.

toward the rear 14 is a short beam mounted upon a truss 15 secured to the axle 10.

v16 is a brace rod extending between the forward end of the short beam 14 and the beam 13 the rear end of the short beam 14 being further connected to the axle 10 by means of a brace rod 17.

18 and 19 constitute a hitch secured to the frame 1 and adapted to be secured to a traction engine or other suitable motor.

20 is a hanger secur-ed to the forward end of the frame 4, to which the forward end of the beam 21 is secured, the rear end of the beam being connected to a fifth wheel 22 mounted upon a frame 23 in which a roller 24 is journaled. The beam 21 is preferably an I-beam.

25 is an arm extending forwardly from the roller frame23 and provided on its outer end with a screw-threaded bearing 26 in which the screw-threaded rod 27 is adapted to be operated to move the roller on the fifth wheel 22 to the proper position with y respect to the other parts of the machine. The forward end of this rod 27 is 'ournaled in a bearing 28 mounted on a brac et 29 secured to the hanger 20.

30 is an operating rod connected by a knuckle joint 31 to the screw rod 27 and 32 is -a hand wheel secured to the rod 30, said rod 30 being journaled in a standard 33 secured to the frame 4. members 3 are secured to a triangular frame The road scraping blade may be of any desired width and composed of any desired number of sections. We prefer to form the l blade in four sections 34, 35, 36 and 37. Section 34 is adapted to form a fiat ditch at the side of the road, as shown in Fig. 6,

while the sections 35, 36 and 37 may be arranged to give the desired grade to the road bed, inasmuch as these blades are flexibly connected as will be hereinafter more fully set forth. While I have shown the ditch blade adapted to form a flat ditch, it is, of course, obvious that it may be shaped to form any shape ditch, but I prefer thetlat ditch as it will not readily wash.

38 is a standard mounted in suitable journals 3S) secured to the roller frame 33.

40 is a frame journaled on the standard 38 and provided at its outer ends with hooks 41 adapted to engage hooks 42 secured to the outer end of the ditch blade 34, whereby said outer end is sustained. The inner end of the ditch blade 34 is flexibly connect ed by means of a hook 43 to one end of the blade 35 which is supported on an arm 44 secured to the frame 1.

45 is a bracket carrying an eye secured to the blade 35 in which the hooked end of the lever 46 is adapted to be engaged, the rear end of the leverbeing pivoted in a bracket 47 mounted on the frame 4. Intermediate its ends, the lever 46 is secured to a rockerl 48 pivoted on the frame 1, the upper end of the rocker being connected by means of a rod 49 to an operating lever 50, pivoted at 51 on a rod 52 suitably secured on vthe frame 4.

53 is a rack quadrant secured to the rod 52.

54is a dog or pawl mounted on the lever 50 controlled by an operating trigger on said lever.

55 are a pair of springs, one end of which is anchored to the rod 48 and the other end anchored by means of a rod 56 to the frame 4, as clearly shown in Fig. 5.

The outer end of the blade 34 is carried, as previously described, on the roller frame 23 and is so arranged that it can be raised and lowered irrespective of the position of the roller, and for this purpose a link 57 is secured to the frame 40 and connected to the end 58 of the bell crank lever 59, which is suitably journaled.

60 is a rod secured at one end to thebell crank lever and at its other end to a slide 6l, the ends of which are turned under the ltop iange of the I-beam 2l, said iiange acting as a guide for the slide. f

62 is a rod connected to the slide at one end, while its other end is pivotally mounted on a pivoted hanger 63, which in turn is connected to a rod 64 pivoted at one end to the hand operating lever 65, which is provided with a suitable ratchet, pawl or dog 66 adapted to engage a quadrant 67 mounted on the frame 4, as clearly shown in Fig. 4.

68 and 69 are two arched hangers, the

outer end of each of which is connected to the blade 35, while their inner ends are suitably secured to the frame 4.

The blade 36 is supported on the outer end of the lever 70, from which depends a link 71 secured at its lower end to a hook 72, which in turn is secured to the blade 36. The lever is pivotally mountedon the frame l in a journal 73, the rear end' of said lever being connected to an arm 74 which is secured to links 75, the rear end of which is connected to the operating lever 76 (see Fig. 5). This lever 76 carries a dog 77 adapted to engage the rack teeth of the quadrant 78.

79 is a coil spring, one end of which is secured to the lever 76, while the other end is anchored by means of an eye 8O to one corner ofv the frame 1.

81 and 82 are beams secured at their outer noaaaoo `ends to the blade 36, lwhile their inner ends are suitably secured to the frame l.

83 is another lever secured to one end of the blade 86 and journalcd at its other end in suitable bearings secured to the frame 1.

84 is an arm secured to the lever 83, which in turn is secured to the rod 85, one end of which is pivotally secured to an operating lever 86 having a suitable dog adapted to engage4 the toothed quadrant 87.

88 and 89 are beams on which the ditch blade 37 is mounted, the inner ends of said beams being suitably anchored to the frame l.

9() is an operating lever having a dog adapted to engage the toothed quadrant 91.

92 is a rod, one end of which is connected to the operating lever 90, while t-he other end is connected by means of a suitable link 93 to a hook 94 fixed to the blade 34.

It will be noted that the beams 89, 88, 81, 82, 69, 68 and 44 are in the nature of plow beams and convey the thrust of the' earth against the blades to the frameof the mal chine.

95 and 96 are suitable foot platforms.

`97 is a foot brace.

98 is a chain connecting the roller frame with one of the blades, so that the roller pulls on this chain and holds the side draft which is adjusted by the screw 27.

Our machine is built for the purpose of grading, ditching, leveling and packing the dirt yon one side of any ordinary road at one operation, using a suitable motor to pull the grader and roller. The frames l and 4 constitute a flexible frame to which the grader blades are attached, said blades being adapt ed to conform to the grade desired for the roa By the use of our machine, grading can be done much faster, and better work can be accomplished at a minimum cost.

The roller, as described, is attached to the extreme back corner of the blade frame and is proivded with a fth wheel, so thatby -means of the guide wheel 32, it willy be guided to roll the center of the road or can be made to run in behind the plow frame for the purpose of narrowing the width of the machine for crossing bridges, and when running the roller directly behind it, carries the blade section attached thereto with it.

All of the blade sections are connected together by a suitable hinge 99, whereby the blades are independently flexible of each other, as shown in Fig. 6, and so arranged that each section of the blade has a separate lever for raising and lowering it, whereby it can be placed in any position necessary to make the desired grade for'the road.

W'hen the roller is set to run in the center of the road, it is held in that position by the chain 98 so that it cannot travel in any other position, and then `by guiding the roller it can be made to crowd toward the center of the road and thereby overcome the side draft tendency of the machine.

The roller 24 is concaved on its rolling surface in order that it 'may give the road an oval shape. Another advantage of this shape is that the ends of the roller bite into the road thus overcoming any tendency t0 slip sidewise; a still further advantage is thatit tends to eliminate the hoisting tendency of the ends of the roller when passing over large clods of dirt.

What we claim is 1. In a road grading machine the combination with a frame, and a series of grading and ditching blades connected to said frame, of a guiding and crushing roller and a connection between said roller and the blades to counteract the side draft tendency of the grading blades. l

2. In a rad grading machine, the combination with a seriesv of frames flexibly secured together, of beams pivotally mounted on said frames, scraper blades carried by said beams and flexibly connected to each other, a roller, a beam, extending from the flexible frame to which the roller is pivoted, steering mechanism extending from the roller to the flexible frame.

3. In a road grading machine the combination with a scraper blade carrying frame, of a roller, a beam, connecting the roller to Asaid frame, said roller being pivotally conframe connected with the other end of said beam, scraper blade beams pivotally mounted on said frame, means to lower and elevate said blade beams, scraper blades secured to said blade beams, a second frame hinged directl to the first-,named frame, scraper blade beams pivotally mounted on the second frame, means to operate the blade 1 beams on the second' frame, scraper blades on the last-named beams, and a traction wheel jurnaled in each of said frames.
